The Trump Administration Defangs the Endangered Species Act
Briefed in the Morning News edition of Monday, 21 September 2026
What was discussed
Trump administration weakens Endangered Species Act protections2:31
- Rachel Abramsassertion
The Trump administration has escalated efforts to roll back environmental regulations, including the Endangered Species Act.
- Catrin Einhornassertion
The administration is stripping a core aspect of the law, telling people they won't get in trouble for killing endangered species so long as they didn't mean to target them.
History and goals of the Endangered Species Act2:04
- Catrin Einhornassertion
The law protects more than 1,600 animals and plants threatened with extinction and prohibits taking them, which includes harassing, harming, or killing. The word 'harm' has been interpreted to include habitat modification, a definition upheld by the Supreme Court in 1990.
1979 Hawaii palila case defines habitat destruction as harm7:53
- Catrin Einhornassertion
A judge ruled that damage to habitat constitutes harm under the Endangered Species Act, setting a precedent that habitat destruction is illegal.
Incidental take permits balance development and conservation9:23
- Catrin Einhornassertion
Incidental take permits allow projects to proceed if developers mitigate harm to endangered species, often through conservation offsets.
1990 Supreme Court case upholds broad harm definition11:28
- Catrin Einhornassertion
The Supreme Court upheld the interpretation that significant habitat modification counts as harm under the Endangered Species Act.
- Justice Scaliaclip
Harm requires intentional targeting of a specific animal, and broad habitat modification interpretations impose unfair financial burdens.
Trump memo requires intent for Endangered Species Act violations15:38
- Catrin Einhornassertion
The memo states that for a death or injury to be illegal, it must be intentional, applying Scalia's dissent broadly.
- Fish and Wildlife Service memoclip
Inadvertent harm, like a vessel striking a whale or felling a tree with bats, is not a violation unless done with the purpose of killing the animals.
Impact of intent requirement on endangered species conservation16:33
- Catrin Einhornassertion
Most endangered animals are killed incidentally, not targeted, so the intent requirement could remove incentives to avoid collateral damage.
- Catrin Einhornspeculation
Some critically endangered species with very low populations could be tipped toward extinction by these measures.
- Catrin Einhornassertion
Habitat conservation plans create ripple effects that nurture many other species, so weakening them has broad indirect impacts.
Legal challenges to Trump administration ESA changes20:39
- Catrin Einhornassertion
Wildlife advocates and states have sued over the changes, and there is concern the conservative Supreme Court could enshrine them.
- Catrin Einhornspeculation
The litigation will likely drag on for a long time even as protections are rolled back on the ground.
Biodiversity loss and economic implications of ESA rollback21:34
- Catrin Einhornassertion
Biodiversity loss is a huge, underappreciated problem that threatens ecosystems essential for a healthy economy. Business organizations have cited biodiversity loss as a huge risk for the economy, challenging the growth-versus-conservation binary.
Trump administration bars news outlets from White House24:43
- Rachel Abramsassertion
President Trump barred CNN, MSNBC, and Politico from the White House, disabling their badges and catching officials off guard.
Trump executive order to control NIH scientific grants24:43
- Rachel Abramsassertion
The White House is drafting an executive order to create a committee that could veto NIH grants not conforming to Trump's political agenda.
